if only shovels where in terraria...
copper-silver shovel breaks weak materials fast
gold breaks a 2x2 area but slowly
nightmare breaks a 2x2 area at a mediumish speed
molten breaks a 2x2 area quickly
cobalt breaks a 3x3 area slowly
mythril breaks a 3x3 area at a medium speed
adamantite breaks a 3x3 area quickly
hallowed breaks a 4x4 area at a medium speed
anyways, nice weapons!
